The People's
Democratic Republic of Yemen (Arabic: جمهورية اليمن الديمقراطية الشعبية‎‎
Jumhūrīyat al-Yaman ad-Dīmuqrāṭīyah ash-Sha‘bīyah), also referred to as
South Yemen, Democratic Yemen or Yemen (Aden) aka South Arabian Federation,
was a socialist state in the southern and eastern provinces of the
present-day Republic of Yemen, including the island of Socotra. Capital: Aden.

It united with the Yemen Arab Republic (commonly known
as "North Yemen") on 22 May 1990, to form the present-day Yemen. After four
years, however, South Yemen declared its secession from the north, which
resulted in the north occupying south Yemen and the 1994 civil war.
In 1838, Sultan Muhsin bin Fadl of the nearby state of Lahej ceded 194 km˛
(75 sq. miles) including Aden to the British. On 19 January 1839, the
British East India Company landed Royal Marines at Aden to occupy the
territory and stop attacks by pirates against British shipping to India. It
then became an important trading hub between British India and the Red Sea,
and following the opening of the Suez canal in 1869, it became a coaling
station for ships en route to India. Aden was ruled as part of British India
until 1937, when the city of Aden became the Colony of Aden. The Aden
hinterland and Hadhramaut to the east formed the remainder of what would
become South Yemen and was not administered directly by Aden but were tied
to Britain by treaties of protection with local rulers of traditional
polities that, together, became known as the Aden Protectorate. Economic
development was largely centered in Aden, and while the city flourished, the
states of the Aden Protectorate stagnated. In 1963, Aden and much of the Protectorate were joined
to form the Federation of South Arabia with the remaining states that
declined to join, mainly in Hadhramaut, forming the separate Protectorate of
South Arabia. Both of these polities were still tied to Britain with
promises of total independence in 1968. Two nationalist groups, the Front
for the Liberation of Occupied South Yemen (FLOSY) and the National
Liberation Front (NLF), began an armed struggle (Aden Emergency) on 14
October 1963 against British control and, with the temporary closure of the
Suez Canal in 1967, the British began to withdraw. One faction, NLF, was
invited to the Geneva Talks to sign the independence agreement with the
British. Ironically, Britain, who during its occupation of Aden signed
several treaties of protection with the local sheikhdoms and emirates of the
Federation of South Arabia, excluded them in the talks and thus the
agreement stated "...the handover of the territory of South Arabia to the
(Yemeni) NLF...". Southern Yemen became independent as the People's Republic
of Southern Yemen on 30 November 1967, and the National Liberation Front
consolidated its control in the country.

In June 1969,
a radical Marxist wing of the NLF gained power and on 1 December 1970,
reorganized the country into the People's Democratic Republic of Yemen (PDRY).
Subsequently, all political parties were amalgamated into the National
Liberation Front, renamed the Yemeni Socialist Party, which became the only
legal party. The People's Democratic Republic of Yemen established close
ties with the Soviet Union, the People's Republic of China, Cuba, and the
Palestinian Liberation Organization. East Germany's consititution of 1968
even served as a kind of blueprint for the PDRY's first constitution. The
major communist powers assisted in the building of the PDRY's armed forces.
Strong support from Moscow resulted in Soviet naval forces gaining access to
naval facilities in South Yemen.
Unlike the early decades of East Germany and West Germany, North Korea and
South Korea, or North Vietnam and South Vietnam, North Yemen (YAR) and South
Yemen (PDRY) remained relatively friendly, though relations were often
strained. Fighting broke out in 1972, and a short-lived, small proxy border
conflict was resolved with negotiations, where it was declared unification
would eventually occur.

However, these
plans were put on hold in 1979, as the PDRY funded Red rebels in the YAR,
and war was only prevented by an Arab League intervention. The goal of unity
was reaffirmed by the northern and southern heads of state during a summit
meeting in Kuwait in March 1979. In 1980, PDRY president Abdul Fattah Ismail
resigned and went into exile in Moscow, having lost the confidence of his
sponsors in the USSR. His successor, Ali Nasir Muhammad, took a less
interventionist stance toward both North Yemen and neighbouring Oman.

On January 13,
1986, a violent struggle began in Aden between Ali Nasir's supporters and
supporters of the returned Ismail, who wanted power back. Fighting, known as
the South Yemen Civil War, lasted for more than a month and resulted in
thousands of casualties, Ali Nasir's ouster, and Ismail's death. Some 60,000
people, including the deposed Ali Nasir, fled to the YAR. Ali Salim al-Beidh,
an ally of Ismail who had succeeded in escaping the attack on pro-Ismail
members of the Politburo, then became General Secretary of the Yemeni
Socialist Party. Against the background of the Perestroika in the USSR,
Yemen's main backer, South Yemen started political reforms in the late
1980s. Political prisoners were released, political parties were formed and
the justice was reckoned to be more equitable than in the North. In May
1988, the YAR and PDRY governments came to an understanding that
considerably reduced tensions including agreement to renew discussions
concerning unification, to establish a joint oil exploration area along
their undefined border, to demilitarize the border, and to allow Yemenis
unrestricted border passage on the basis of only a national identification
card. In 1990, the parties reached a full agreement on joint governing of
Yemen, and the countries were effectively merged as Yemen.

Since 2007,
Southerners have been actively protesting for independence, in a movement
known as 'Al Hirak' or the Southern Movement. During the Yemen Civil War
2015, in response to incursions by the Houthis and military forces loyal to
deposed Yemeni president Ali Abdullah Saleh, members of the Southern
Movement formed 'Popular Resistance' militias. Since the Battle of Aden,
these armed groups have sought to defend the South against Houthi/Saleh
attempts to take over the country and have taken the current state of civil
war as opportunity to further their struggle for independence.

Currency:
The dinar (Arabic: دينار‎‎) was the currency of South Arabia and then South
Yemen between 1965 and 1990. Code: YDD (ISO 4217). It was subdivided into
1000 fils (فلس). After Yemen's monetary unification on 1 July 1990, it was
one of the two official currencies used in Yemen Republic until 11 June
1996.
The dinar was introduced in 1965 as the South Arabian Dinar, replacing the
East African shilling at a rate of 1 dinar = 20 shillings, thus setting the
dinar initially equal to the British pound. It was renamed the South Yemeni
dinar after the Aden Protectorate became independent in 1967 as the South
Yemen. The South Yemeni dinar was replaced by the rial following unification
with North Yemen. The exchange rate was 1 dinar = 26 rial. Dinar banknotes
remained legal tender until 1996. In 1965, coins (dated 1964) were
introduced for South Arabia in denominations of 1, 5, 25 and 50 fils. The 1
fils was struck in aluminium, the 5 fils in bronze and the higher two
denominations in cupro-nickel. In 1971, coins were issued in the name of
"Democratic Yemen", changing to the "People's democratic Republic of Yemen"
in 1973. That year, aluminium 2˝ fils were introduced, followed by aluminium
10 fils and cupro-nickel 100 and 250 fils in 1981. The 10 fils was scalloped
shaped whilst the 100 fils was octagonal.
